Activated whenever a 32-byte FIFO pool is
empty and accessible to the CPU, i.e.
– following a XRES command via CMDR.
Interrupt Mode:
Repeatedly during frame transmission started
by XTF or XIF command, and no end of
message indication (XME command) has
been issued yet by the CPU,
– after the end-of-message indication
when frame transmission of a transparent
frame is completed (i.e. CRC and closing flag
sequence are shifted out),
Auto-Mode:
If
acknowledged by the opposite station.
Auto-Mode:
Activated if the last transmitted I-frame has to
be repeated due to the reception of a negative
acknowledgement
unaccording receive sequence number) of the
opposite station.
Bus Configuration:
A collision has occurred after sending the
32nd data byte of a message.
Point-to-Point Configuration:
CTS has been withdrawn after sending the
32nd data byte.
Activated if the XFIFO holds no further data,
i.e. all data has been shifted out via the serial
T D pin, but no End Of Message (EOM)
indication has been detected by the HSCX.
The EOM indication is supplied either
– by a XME command from the CPU in
Interrupt Mode,
– or by checking the pre-programmed
transmit byte count (via XBCH, XBCL) against
the actual amount of data bytes shifted out in
DMA Mode.
